BIRD-PERCH.

SPECIFICATION forming part of Letters Patent No. 276,392, dated April 24, 1883.

Application filed December 5, 1882. (ModeL) To all whom it may concern:

Beit known that I, FRED LEON GREGORY,

I of Neligh, in the county of Antelope and State is hung.

of Nebraska, have invented a new and Improved Bird-Perch, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved swinging perch for bird cages.

Reference is to be hadto the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view ot' my improved bird-perch, parts being shown in section. Fig. 2 is a side view of the same. Fig.3 is adetail view of the apertured plate through which the knife-edge bar passes, on which the bracket A rod, A, is provided with a series of transverse arms, B, which may be straight or curved at right angles to the rod A, or inclined to the same, and made of wood or metal. Preferably they consist of wooden rods secured to short arms projecting from the rod A. The lower end of the red A is screw-threaded, and a ball, 0, which has a threadedaperture, is screwed on the threaded lower end of the rod, to permit adjusting the said ball higher or lower. The ball may be replaced by a heavy perch or arm, or by any other suitable balancingweight, which may be made fixed or adjustable, and which may be made more or less ornamental. It serves to balance the weight of the birds on the arms or perches and to bring the rod A into the vertical position. A knife-edge bar, D, is attached to the end of a bracket, E, in such a manner that it will proj g horizontally from the end of the same, d will also project in the same direction as the bracket. Arms or perches F are attached to the ends of the knife-edge bar D, which passes through an aperture, G, in a plate or block, H, secured to the rod A, which plate or block is provided with an aperture, which I is contracted at its upper part, J, to form a bearing for the knife-edge bar, its lower part, G, being of a size to admit of passing the plate over the arm F. The bracket E is to be provided at its inner endor base with screw-holes for screw s to secure the bracket to the wooden back of a cage, or with latches to secure it to the wires of the cage. The bracket can easily be attached and detached from a cage.

7 The rod A can rock on the knife-edge of the bar D, and as its lower part is heavier than its top it will always assume a vertical position.

The number of arms or perches B may be greater or less, and the length of all the parts may be varied, as circumstances may require.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A swinging bird-perch having an adjustable balancing-weight held on its lower end, substantially as herein shown and'described, and for the purpose set forth.

2. The combination, with the rod A, having an apertured plate or block, H, of the arms B and the bracket E, having a knife-edge bar, D, substantially as herein shown and described, and for the purpose set forth. l

3. The combination, with the rod A, having an apertured plate, H, of the arms B, the bracketE, having a knife-edge bar, D, and the arms F, attached to the bar D, substantially as herein shown and described, and for the purpose set forth.

4. The combination, with the red A, having an apertured plate or block, H, and having its lower end screw-threaded, of the arms B, the bracket E, and the weight 0, screwed on the lower end of the rod A, substantially as herein shown and described, and for the purpose set forth.
